Iiphampu yamanzi kagesiIlungisa ukuhamba kwe-coolant ejikelezayo ngokwezimo zokusebenza zemoto futhi iqaphela ukulawulwa kwezinga lokushisa kwemoto yemoto. Iyingxenye ebalulekile yesistimu yokupholisa yemoto entsha yamandla. Ukuhlolwa kokusebenza kuyingxenye ebalulekile yocwaningo nokuthuthukiswa nokukhiqizwa kwephampu yamanzi. Njengamanje, ukuhlolwa kwephampu yamanzi kagesi yezimoto Ucwaningo lobuchwepheshe kanye nokuthuthukiswa kwemishini akuhambisani nokuthuthukiswa kwamaphampu amanzi kagesi, futhi ucwaningo ngamasu okuhlola lugxile kakhulu kumaphampu amanzi endabuko. Uhlelo lokuhlola iphampu yamanzi elincane le-NF lungalinganisa amapharamitha okusebenza njengokugeleza kwephampu, ukuphakamisa, kanye nokusebenza kahle kweshafu ekushiseni kwegumbi, futhi lubone idatha yokuhlola. Iqoqo elisheshayo lokuqina komoya wephampu yamanzi. Ibhentshi lokuhlola ukuqina komoya wephampu yamanzi eliklanyelwe kalula lisebenzisa ingcindezi ehlukile ukuthola ukuqina komoya wephampu yamanzi. Uhlelo lokuhlola olujwayelekile lwephampu yamanzi luklanywe ngokusebenzisa amasekethe afakiwe kanye nalawo analog.
Ngokwezindinganiso zomkhakha i-QC/T288.2-2001 kanye ne-JB/T8126.9-2017 kanye nezidingo zenqubomgomo ezihlobene, ukuhlolwa kohlobo lwephampu yamanzi okupholisa kufaka phakathi ukuhlolwa kokusebenza, ukuhlolwa kwe-cavitation, njll. Ngokuhlola izinga lokugeleza, i-voltage, kanye ne-Current, ingcindezi yokungena kanye neyokuphuma, ukubalwa kwekhanda, amandla, ukusebenza kahle, i-NPSH kanye neminye imingcele yokusebenza, qedela umdwebo wejika lokusebenza kwamaphampu amanzi kagesi.
Ngokungafani nephampu yamanzi okupholisa yomshini, isivinini se-iphampu yamanzi kagesiilawulwa uhlelo lwayo oluhlanganisiwe, futhi i-voltage enikeziwe kanye nesignali yokulawula kungenza i-DC brushless motor yangaphakathi isebenze ngesivinini esihambisanayo. Indlela yendabuko yokuhlola i-torque yemoto kanye nesivinini sokubala amandla okufaka ephampu yamanzi ayifaneleki ku-elekthronikhi. Ekuhlolweni kwephampu yamanzi, ifakwe ugesi ohleliwe ukuze ifunde emuva i-voltage lapho iphampu yamanzi isebenza, ibale amandla okufaka emoto ngokusebenzisa ugesi kanye ne-voltage, bese uyiphindaphinda nge-efficiency coefficient ukuze ibe amandla okufaka ephampu yamanzi kagesi.
Amapharamitha obuchwepheshe ayinhloko ohlelweni lokuhlola: ububanzi bokulinganisa ukugeleza 0~500L/min, ukunemba kokulinganisa ±0.2%FS; ububanzi bokulinganisa ingcindezi yokungena kanye neyokuphuma -100~200kPa, ukunemba kokuhlola ±0.1%FS; ububanzi bokulinganisa bamanje 0~30A, ukunemba kokulinganisa ±0.1 %FS; ububanzi bokuphakelwa kwamandla kagesi angahlelwa 0~24V, ukunemba kokufunda ±0.1%FS, ububanzi bamandla 0~200W; ububanzi bokulinganisa izinga lokushisa -20~100℃, ukunemba kokulinganisa ±0.2%FS, ububanzi bokulawula izinga lokushisa 0~80℃, ukunemba kokulawula ±2°C.
Uhlelo lokuhlola ukusebenza olujwayelekile
Ngokwezindinganiso zokuhlola zemboni ezifanele, ukuhlolwa kokusebenza okujwayelekile kwamaphampu amanzi kudinga ukuthi ngaphakathi kwebanga elingu-40% ~ 120% wejubane elilinganisiwe lephampu, amaphuzu okusebenza okugeleza okungenani angu-8 kufanele abekwe ngokulinganayo ngokwezinga lokugeleza eliphezulu nelincane elidlula ephayiphini lokuhlola. Ngokusebenzisa i-PID control, Lungisa ukuvulwa kwevalvu elinganayo yokukhipha ukuze kuzinziswe ukugeleza endaweni yokugeleza. Inzwa iqapha ingcindezi yokungena neyokuphuma, izinga lokushisa, izinga lokugeleza kwephayiphi lokuhlola iphampu yamanzi kagesi ngesikhathi sangempela, kanye namanani epharamitha yokusebenza kanye namanani wamanje ephampu yamanzi kagesi. Lapho i-flowmeter iqapha ukuthi ukugeleza ephayiphini kuzinzile Ngemva kwesikhathi esithile, bhala phansi amanani epharamitha ephampu yamanzi kagesi. Ukwazi ububanzi bephayiphi, umehluko wokuphakama phakathi kokungena neyokuphuma, amapharamitha wobuningi boketshezi kanye nokusheshisa kwamandla adonsela phansi, bala ama-flow-head, amandla okugeleza, kanye nama-flow-efficiency curve ephampu yamanzi kagesi ngesivinini esilinganisiwe ｡
